Yes, there is a celestial object called Sedna (90377 Sedna), which is a dwarf planet candidate orbiting far beyond Neptune and Pluto. Its closest approach to the Sun is about 1.5 times the maximum for Pluto, with an extreme elliptical orbit varying from 76 AU to 975 AU.
As the farthest identified object orbiting the Sun, Sedna takes about 12,000 Earth years to complete one orbit. It will reach its next closest approach to the Sun in the year 2075. Only the dwarf planet Eris is current farther from the Sun.
Its size is estimated at approximately three-quarters the size of Pluto, or about 1,000 miles (1200-1600 km) in diameter.

More on Sedna
Sedna rotates very slowly. It takes at least 20 days to complete a rotation, maybe as long as 50 days. The gravitational pull of a moon would be the best explanation for this slow rotation. Almost all other minor bodies in the solar system rotate in a matter of hours. Pluto has a six-day rotation because it has a satellite, Charon. But Sedna has no moon.
No, Sedna does not have any known moons. Sedna is a distant dwarf planet located in the outer regions of the solar system, beyond the Kuiper Belt. It has not been observed to have any natural satellites orbiting around it.
Sedna, the astronomical object 90377 Sedna is a strong candidate, but is not officially a dwarf planet.
The currently classified dwarf planets are Ceres (asteroid), Pluto, Eris, Makemake, and Haumea.
Not officially. It is still classified as a planetoid, though it has been considered for dwarf planet status.
No. Sedna is currently classified as a planetoid. It is being considered for classification as a dwarf planet.

How many moons does sedna have?
Sedna does not have any moons. It is a planetoid located in the outer reaches of the Solar System beyond the Kuiper Belt.
Does planet sedna have any rings or moons?
Planet Sedna does not have any rings and as of current scientific observations, it does not have any known moons either. Sedna is a small, icy dwarf planet located in the outer reaches of our solar system, beyond the orbit of Neptune.
What gases make up Sedna's atmosphere?
It is believed that Sedna, a distant dwarf planet in our solar system, does not have a significant atmosphere due to its extreme distance from the sun. Therefore, it is unlikely to have any gases that make up an atmosphere similar to that of planets closer to the sun.
Will Astronomers find evidence of life on Sedna?
It's very unlikely.
Can you live on sedna?
No, it is not possible to live on Sedna because it is a distant and frigid dwarf planet located in the outer regions of the Solar System with extremely cold temperatures and no known atmosphere to support life as we know it.
How many moons does sedna have?

What is sedna and how can be the scientist prove that sedna is a new planet or just the moon of Pluto?
Sedna is a dwarf planet. It is to far away to be one of plutos moons and is proved to orbit the sun
What is a sedna?
Not "a" Sedna; just "Sedna". Sedna is the Inuit goddess of the sea. Also, a dwarf planet named after this goddess.
Which is further sedna or Eris?
Sedna
What consist the solar system?
The Sun, Mercury, Venus, Earth, Mars, Asteroid belt, Ceres (dwarf Planet inside the Asteroid belt) Jupiter, Saturn, Uranus, Neptune, Start of Kuiper belt (Dwarf planets Pluto, 2003 EL, Eris and Sedna). Jupiter is the largest planet and it also has the most moons: 63 Saturn has 56 moons Uranus has 27 Neptune has 13 Mars has 2 Earth has 1 and venus and mercury have none. Dwarf planets. Pluto has 3 moons 2003 EL has 2 moons Eris has 1 moon Sedna has none as far as astrologists know. But Sedna has an orbit lasting 10,500 years and is the coldest known place in the solar system.
Is sedna an asteroid?
No. Sedna is currently classified as a planetoid.
How many km is sedna from sun?
There is not a way to tell how many km are from the sun to Sedna. It is a long distence from the sun to Sedna.
What is sedna's Landscape?
Sedna is a small DWARF planet made of ice and rock.
Is Sedna one of Saturn's moon?
Sedna is not a moon of Saturn. It is a dwarf planet that is located in the outer parts of the Solar System. Sedna was discovered in 2003.
Does Sedna also orbit around other dwarf planets?
No. Sedna orbits the sun.
